High Voltage 3-Phase Full-Wave PWM Brushless Motor Driver

The project presented here is a three-phase sinewave PWM driver for high-voltage brushless motors. The board is built using TB67B000AHG chip, which is a high-voltage IC capable of handling 600V. The TB67B000AHG has a 2-in-1 (MCP) structure of controller (sine-wave PWM / wide-angle conduction) and a high-voltage driver. The rotation speed of a DC brushless motor can be controlled directly by the speed control signal (analog voltage) by an onboard trimmer potentiometer or from a microcontroller. The board supports a 3-phase BLDC motor with Hall sensors. On Board Trimmer, the potentiometer helps users to control the speed of the brushless motor.
